running into issues with RVM during Ruby install (

I'm trying to install ruby via RVM and am getting the following error and the logs are not really clear as to what's going on, has anyone run into this? I seem to recall that Ruby should not be installed as root but I'm a bit suspicious of the permissions error that I'm getting.

I had the same error message, and i resolved it by doing sudo chown -R user:user /usr/local/rvm where user is your logged in user, after that i ran rvm install 1.9.2 and it completed successfully.

回答2:

I like the solution above but instead of using user:user do user:rvm.

Make sure you've added your user to the rvm group. Also, make sure you log out and log in. Group memberships are processed at login, so in order to write to /usr/local/rvm, you must log out and then log in so that the OS recognizes that you're in the rvm group.

The error seems to be

Failed to create the file ruby-1.9.2-p290.tar.bz2: Permission denied

Did you try to do something with sudo one time? You want to make sure that /Users/mark/.rvm/rubies/ is writable for your user.
